Device for Reseating Valves and Faucets, of

which the following is a specification.

My invention has for its object to provide an implement for reseating valves and faucets which may be used by any person, whether skilled or unskilled, without other tools than a wrench and which will enable him to repair all ordinary kinds and styles of valves and faucets without removing other parts than the cap-stem and disk, my novel device being especially adapted for use in repairing ordinary water-faucets, as it enables the operator to repair a faucet very quickly and efiectually without removing it from its lace. p It is of course well understood that the seats of ordinary water-faucets, especially if there is any sediment or particles of soil in the water, frequently become scratched by particles and then quickly wear away, so as to cause leakage and dripping of the faucets. The ordinary mode of making repairs is to put in new washers or a new valve-disk, but without in any way changing the contour of the valve seat. Repairs of this kind are 7 sometimes efiective for a short time, but

quickly have to be renewed, and not infrequently it is found impossible to make effective repairs, and the faucets must be thrown away and new ones substituted in their place. With my resent device I have taken faucets that ad been thrown away as absolutely useless and after grinding a new concave valve-seat and providing a correspondingly-shaped valve-disk have found the faucets to be absolutely tight and free from dripping after many months of continuous service.

My novel reseating device consists, essentially, of a convex rotary cutter carried by a shank which is adapted to pass through the ordinary cap of a valve or faucet, and is providedwith a tapering bearing-piece adapt-v ed to engage the inner side of the cap centrally to insure the centering of the cutter upon the valve-seat. This cutter maybe operated by a finger-piecefor example, the

ordinary finger-piece or wheel of the valve or faucet that is being repaired.

With the above-stated and other objects in view I have devised the novel reseating device which I will now describe, referring to the accompanying drawings, forming part of this specification, and using reference characters to indicate the several parts.

Figure 1 is a longitudinal section of'an ordinary water-faucet with my novel reseating device applied thereto and appearing in elevation, the starting position of the parts in forming a new valve-seat appearing in dotted lines and the full-line position indicating the position of the parts when the new seat is finished. Fig. 2, a detailview, on an enlarged scale, showing a finished concave valve-seat as formed by my novel cutter with a correspondingly-shaped valve-disk in engagement therewith; and Fig. 3 is a similar view showing the cutter in position to commence the cutting of a new valve-seat.

10 indicates the body of a valve or faucet, in the present instance an ordinary waterfaucet, which is provided with an internal thread 11 to receive the thread (not shown) upon a valve-stem 12.

13 in Fig. 3 denotes an ordinary valveseat before the reseating operation has been performed, and 14 in Figs. 1 and 2 indicates a concave valve-seat as ground by my novel reseating device.

15 denotes the ordinary cap of a valve or faucet, which is-provided with an internal screw-thread 28 to engage a corresponding external screw-thread at the top of the body, and 16 denotes the ordinary finger-piece of a valve, which is provided with the usual angular openin to receive the angular upper end of the valve-stem and is shown in Fig. 1 as in engagement with the shank of the reseating device.

17 denotes the cutter of my novel reseating device, which is rigidlysecured to a shank 18. This shank is made long enou h to extend through the caps of ordinary va ves and faucets and extend above the top thereof, the upper end of the shank being provided with an angular portion 19 to receive a fingerpiece, which may be the ordinary finger-piece of the valve, as in Fig. 1, or a special handpiece may be provided, if preferred.

20 denotes a sleeve, 21 washers, and 22 a tapering bearing-piece, all of which slide freely but closely over the shank, as clearly shown in Fig. 1.

The operation of reseating a valve or faucet is as follows: The operator first removes the cap of the valve or faucet and then turns out the stem carrying the disk. The operator then inserts the cutter, placing it in engagement with the valve-seat and places the sleeve and the bearing piece and between them a plurality of washers, if required, upon the shank. He then places the cap in engagement with the body, but does not, of course, turn it down to place, and places a suitable finger-piece, which may be the fingerpiece of the valve or other suitable operating device, upon the upper end of the shank. In starting it is necessary that the cutter should just be centrally in engagement with the opening 25 in the valve-seat, as in Fig. 3, and that the cap should just be engaged with the thread at the upper end of the body, as indicated by dotted lines in Fig. 1. In order to effect this adjustment, as many washers as maybe required are placed between the sleeve and the bearing-piece, the sleeve being provided sim ly to avoid the use of an unnecessary number of washers between the cutter and the bearing-piece. By making the upper end of the bearing-piece tapering, as at 23, and of greater diameter than the opening 24 in the cap I insure that the cutter will be self-centering relatively to the opening 25 in the valve-seat. The operation of grinding the new valve-seat is effected by rotating the shank carrying the cutter and turning down the cap on the body as fast as the rinding operation proceeds. The turning down of the cap through the engagement of the bearing-piece therewith of course forces the cutter down upon the valve-seat as the cap is turned downward on the body, thus enabling the operator to complete the operation of grinding a new valve-seat very quickly without removing the cutter and without any additional adjustments. Having formed the new valve-seat, the operator turns off the cap and removes the shank and the cutter.

A new valve-disk 26, having a convex curvature corresponding with the concave curvature of the new seat, is attached to the stem by means of a screw 27 or in any suitable manner. The stem, disk, and cap are replaced as before, and the valve or faucet is ready for use.

In practice the valve-disks may be made of any suitable material; but I recommend lignum-vitae, as I have used it to a considerable extent and find it admirably adapted for the purpose. I find that the combination of a lignum-vitae convex valve-disk with a concave metallic valve seat produces a very durable and absolutely tight valve or faucet.

Having thus described my invention, I claim- 1. A device of the character described comprising a convex cutter a shank therefor and a bearing-piece which slides over the shank, and is tapered at its upper end for engagement with the opening in a valve or faucet cap whereby the cutter is made self-centering on the seat of a valve or faucet.

2. A device of the character described comprising a convex cutter, a shank therefor, a sleeve adapted to slide over the shank and rest upon the cutter, a bearing-piece adapted to slide over the shank and having a taper at its upper end to engage the opening in a valve or faucet cap and washers intermediate the sleeve and bearing piece whereby the parts may be so adjusted that the cutter will engage centrally the opening in the valve-seat when the cap is in engagement with a valve or faucet body, and turning down of the cap upon the body will force the cutter downward upon the valve-seat as the operation proceeds.

3. A device of the character described comprising a convex rotary cutter, a shank by which it is carried, a bearing-piece adapted to engage the shank and having a taper to engage the cap centrally and means for retaining the bearing-piece in engagement with the cap when the cutter is in engagement with the valve-seat, so that by rotation of the cutter and turning down of the cap upon the body a new concave valve seat will be formed.

4. A device of the character described comprising a convex cutter, a shank therefor, a sleeve adapted to slide over the shank and rest upon the cutter and a bearing-piece adapted to slide over the shank and having a taper at its upper end to engage the cap centrally and center the cutter upon the valveseat.

5. A device of the character described comprising a cutter, a shank therefor and a bearing-piece which slides over the shank, and is tapered at its up er end for engagement with the opening in a valve or faucet cap whereby the cutter is made self-centering on the seat of a valve or faucet.

6. A device of the character described comprising a self-centering cutter, a shank therefor, a sleeve adapted to slide over the shank and rest upon the cutter, a bearingpiece adapted to slide over the shank and having a' taper at its upper end to engage the opening in the valve or faucet cap, and washers intermediate the sleeve and bearingpiece whereby the parts may be so adjusted that the cutter will engage centrally the opening in the valve-seat when the ca is in engagement with a valve or faucet ody, and turning down of the cap upon the body will force the cutter downward upon the valveseat as the operation proceeds.

7. A device of the character described comprising a self-centering rotary cutter, a shank by which it is carried, a bearing-piece adapted to engage the shank and having a taper to engage the cap centrally and means for retaining the bearing-piece in engagement [O ing-piece adapte with the cap when the cutter is in engagement with the valve-seat, so that by rotation of the cutter and turning down of the cap upon the body a new valve-seat will be formed.

8. A device of the character described comprising a self-centering cutter, a shank therefor, a sleeve ada ted to slide over the shank and rest u on t e cutter and a bear- 5 to slide over the shank and having a taper at its upper end to engage the ca centrally and center the cutter upon the va ve-seat.

In testimony whereof I afiiX my signature in presence of two witnesses.
